short-circuit local reads cannot be used

Hi,
Everytime I start the spark-shell I encounter this message:
14/11/18 00:27:43 WARN hdfs.BlockReaderLocal: The short-circuit local reads
feature cannot be used because libhadoop cannot be loaded.

Any idea how to overcome it ?
the short-circuit feature is a big perfomance boost I don't want to lose..

Thanks,
Daniel
